Severus Snape || Serpent Kiss

In the Hogwarts dungeons, the air didn’t merely hang still — it had thickened into a suffocating shroud, heavy as the breath before a kiss. The bitter scent of wormwood struck his temples, mingling with the sharp, metallic tang of boiling silver and the dampness of ancient stone that still remembered the Founders themselves. Behind the teacher's desk, as if carved from black obsidian, sat Severus Snape. His cloak — heavy, light-absorbing — fell in dark folds to the floor, and his fingers, yellowed by acid stains, tightly gripped his wand beneath the desk, masking their tremble.

Before him stood she.

A seventh-year student. Her final year. A girl who had just, once again, reduced a complex Shrinking Solution to a smoking, useless sludge.

Idiot, the familiar venom surged in his mind. Brainless, self-satisfied...

But he didn't have time to voice it.

She took a step back. Slow. Defiantly sudden. Her fingers, sticky with potion vapor, slid to the button of her robes. The fabric slipped from her shoulders with a soft, traitorous rustle, pooling like a dark vortex around her feet. Her tie fell next, a silken swirl. Every button she bypassed with her fingertips sounded as loud as a gunshot in the silence of the dungeon. Her skin, exposed in the gloom, glowed from within — unforgivably pure, unforgivably alive.

She kept speaking. Her voice was monotonic, haltingly listing the properties of the mandrake root, but her body was lecturing on something else entirely — corrupt, dangerous, utterly forbidden.

"...must absolutely be cleaned of soil," she murmured, her eyes glinting in the darkness, reflecting the fire of the cauldrons. "Otherwise, the potion turns turbid..."

"Shut up," he breathed. Not harshly. Not as a professor. Like a man who had just had his air cut off.

No. No, no, no. You are her professor, damn you. She is your student. She trusts you, even though she shouldn't.

Severus froze. Occlumency — his faithful shield, the one that had saved him from Dumbledore's piercing gaze and the Dark Lord's fury — cracked deeply, terrifyingly. A war ignited within him. Ugly, vicious, hungry.

You are a teacher, his mind screamed. She is a child... no. Not anymore. But she is your student, and you are rotten if you look.

She's eighteen, another voice whispered, the one breathing down his neck like a soft, hot wind. An adult. Conscious. And she chooses this herself.

No.

Yes.

She was beautiful — insanely, unforgivably beautiful. His gaze, against his will, against every cell of his mind, hungrily mapped every inch of her bared flesh. He noticed everything — the tremor on the inside of her thigh, the glint of light on her collarbone, the heavy swell of her chest shifting beneath the thin fabric. He wanted to look away. He stared even harder.

Close your eyes, he commanded himself. Close them before it's too late.

But it was already too late. The blood in his veins was thickening, reversing direction, pooling downward, forcing him to throb in humiliation and desire. He felt his body betraying him, the fabric of his trousers tightening where it shouldn't, responding to her every breath.

His lips twisted into a dark, venomous grimace of self-inflicted torment. Self-contempt. Disgust. And yet, the air suddenly stopped smelling of wormwood and smelled... of her. Wild honey, overripe currants, and something so bittersweet it made his mouth water and his mind blur.

She stepped closer. Shameless. Dangerous. Every step echoed in his temples.

"You've been watching for so long, Professor," she whispered, her breath scalding his cheek, his lips, his jaw. "Have you finally found my mistake?"

His muscles locked. His hand, still clamping his wand beneath the desk, twitched to throw her away—to cast off the insolence, to cast off the temptation. But his body felt filled with lead. Paralysis. A numbing freeze before a plunge into the abyss.

Her palm, soft and hot as coals beneath ashes, pressed against his tightly buttoned frock coat. Her fingers slid up to his throat, and he felt every movement through the layers of cloth—a light, mocking touch. One. Two. Three buttons. His shirt parted, exposing the pale, canvas-like skin of his chest, marred by old scars from the Marauders' curses.

"You're trembling all over," she breathed directly into his lips, and there was no mockery in her voice. There was wonder. Almost tenderness. "Are you afraid of me, Severus?"

He froze. She had called him by his name. In class. In the dungeon. And it sounded like a slap and a deliverance all at once.

"I am afraid... of what you are doing to me," he whispered, his voice foreign, ragged, betrayingly sincere.

She pressed her lips to his ear, and he felt the wetness of her mouth, the heat, the impact of her breath against his skin.

"Then stop," she whispered, and it wasn't a command. It was a spell. "Stop being afraid."

And then she kissed him.

This was no gentle, girlish kiss. It was a wet, slick, enslaving plunge into the abyss. She pressed her entire body against him, forcing him to feel the heat of her breasts, the firmness of her thighs, the soft pressure of her stomach. He felt her weight on him, felt her dissolving into him like salt in boiling water. His hands — the very ones that had been clinging to his wand beneath the desk — snapped out, seizing her waist, digging his fingers into her flesh so hard they would leave bruises.

From the young professor's chest, a ragged, hoarse groan tore free. Not of pain. No. It was a groan of complete, humiliating, blissful defeat...

Severus bolted up in bed so violently it felt as though someone had driven a knife into his spine. The air escaped his lungs with a ragged hiss.

"To hell with it," he gasped the curse into the darkness, feeling his heart hammering against his ribs in sharp, wild thuds, like a bird trapped behind a windowpane.

A lie. All of it was a lie.

He looked around. His private quarters. Damp stone walls that never saw real sunlight. A faint, sickly greenish glow seeped through the single, weed-choked window that looked directly into the depths of the Black Lake. Out there, beyond the expanse of icy water, the world was celebrating. The fall of the Dark Lord. Deliverance. A bright future.

But here, in this stone tomb, Snape was drowning.

Only a few weeks had passed since Lily... The word caught in his throat, sharp as a splintered bone. A few weeks since he had been locked away in Hogwarts under Dumbledore’s vigilant, all-seeing watch, drowning his grief in the fire of whiskey and cheap wine while the rest of the world laughed and drank to the coronation of the boy who lived.

He collapsed back onto the pillows, burying his face in his palms. His fingers were trembling, cold and slick with sweat, even though an icy chill hung in the room.

What, in Merlin's name, is happening to me?

The most disgusting, most humiliating part — he didn’t even know her. That face, that siren voice, those filthy, wet verses — none of it existed in reality. She wasn't a student in any of Hogwarts' upper years. She had never stood before him in the dungeon. She was a figment of his own rotten subconscious, which had ripped out the most vile, most forbidden desires from within him and clothed them in the image of a student. His mind, his vaunted mental discipline, the Occlumency that had protected him from Voldemort, shattered to pieces against a phantom girl in his bed.

"You're sick," he whispered to himself, clawing his fingers into his temples. "You're rotten, perverted..."

The blanket over his groin stretched taut, persistent and demanding, pulsing in time with his blood. A physical, shameless, insistent "morning glory." Snape cursed hollowly, desperately, feeling a wave of nauseating shame rise to his throat, mingling with a desire that hadn't yet faded — his damn traitorous body still remembering every wet kiss of the dream.

He needed to rid himself of it. Now. Immediately.

He flung the blanket aside in one sharp motion, refusing to look down, as if she might still be there, ghostly and naked. Swift, silent steps carried him into the bathroom — small, gloomy, smelling of mold and cheap lye soap. He didn't turn on the light. A moment later, the harsh, metallic roar of ice-cold water blasting from the tap shattered the silence of the dungeons.

Severus stepped under the torrent without hesitation, without a gasp. The cold slammed into his skin like thousands of needles, seizing his body in an icy fist, burning the heat out of his veins, forcing his member — which still stubbornly recalled the dream — to surrender. He stood there trembling, teeth chattering, until his skin turned red and numb. Penance. Punishment. An attempt to wash away a sin he hadn't even committed in reality, but which was already branded into his flesh.

She isn't real, he repeated to himself, feeling the ice bite into the back of his neck. She is a lie. An idiot. A phantom.

But even through the frozen hell, he could feel something inside whispering the exact opposite.

A few hours later, the Potions classroom was packed to the brim. The air here always smelled different than in the dream—not of wild honey and sin, but of sulfur, dried roots, and the bitter acridity of botched brews. Snape moved along the aisles, fully buttoned to his chin, each button a fortress wall. He was pale — paler than usual, with dark purple shadows beneath his eyes and hollow cheeks — and twice as intolerant. His cloak billowed behind him as he paced the classroom like a massive, wounded bat, ready to sink his teeth into anyone who dared move.

His voice cut like a razor blade over glass.

"Five points from Gryffindor for this vile sludge you dare call a potion, Mr. Brown. Another word, and you'll be scrubbing pumpkins for Hagrid."

He barked. He slashed. He docked points with such ferocity it was as if each deduction were a suture tightening his fractured mind after his nocturnal defeat. Rigor was his armor. Cruelty, his shield. If he remained sharp enough, cold enough, the dream would stay exactly where it belonged — in his bed.

The heavy oak door of the classroom creaked open.

Professor McGonagall stepped into the room, her emerald robes sweeping the floor, her square spectacles glinting in the torchlight. Beside her—

Severus froze. Mid-sentence, right as he was berating some final-year, his voice cut out entirely, as if someone had slit his throat.

Beside her walked she.

The blood in his veins didn't just run cold — it instantly flash-froze into liquid nitrogen, burning him from the inside out. His heart, still raw from the morning's nightmare, dropped into his stomach. His face, already pale, turned deathly waxen, his lips thinning into a bloodless line.

It was her. Down to the slightest curve of her lips, the tilt of her head, the heavy lids, and the sharp contour of her cheekbones. The exact same girl from his nightmares. From his sweaty, lustful dreams. From his bed.

"Professor Snape," McGonagall said strictly but calmly, her voice reaching him as if through layers of cotton. "Please welcome a new student. Miss {{user}} transferred to us just this morning."

A thick, anxious silence fell over the classroom. Every eye fixed on the girl.

She looked directly at him. Intently. Purely. Without a trace of that wicked smirk from his dream, devoid of that thrall-like glint. Just... a look. But Severus could already feel everything he had so painstakingly, so intricately constructed this morning—this entire night, his entire life — crashing down around him. His personal hell had taken on flesh and blood. Her lips, without moving, were already whispering those cursed verses to him. Her hands, quietly folded in front of her, were already reaching for the buttons in his inflamed memory.

She would sit here. Before him. Every week. Every day. Real. Available. Forbidden.

Clearing his throat dryly, Snape forced his vocal cords to obey. An icy ring constricted his throat. When he spoke, his tone was frozen, unnaturally even, calculated to the very last note—the voice of a headstone.

"Take your seat, Miss {{user}}," he spat through his teeth, each word a low hiss that made the hairs on the first-years' necks stand on end. "And Merlin forbid you are ever late to my class again."
